    (54) Use of crosslinkable hot melt adhesive compositions


    (57) A hot melt composition based on prepolymers containing isocyanate groups and trimerization catalysts and intended in particular for the adhesives and sealants sector is described which when applied is able, by means of a cross-linking reaction, to develop high mechanical strength and heat resistance in an extremely short time independently of the environmental humidity conditions. The composition can also be used in the coating, impregnation and laminates sectors.
